I did an interesting test yesterday that I believe would be able to somewhat determine the internal resistance and health of the pack.
I have a full time voltmeter on my pack.
I was idling, pack at 158V no current in or out.
I revved the engine by using MIMA assist to put the full 100A into the IMA motor. The 158V dropped to 138V under the 100A load.
This voltage drop mostly represents the packs internal resistance.
After a short burst of assist,I let it idle again and the pack settled back to ~ 156V in less than a minute.
If we had several people repeat the test, we could compare numbers and see if the test tells us anything.
